VEHICLE-AXLE.

SPECIFICATION forming part of Letters Patent No. 316,439, dated April28, 1885 I Application filed October 27, 1884. (No model.)

To aZZ whom it may concern:

Be it known that we, STRONG M. BENNETT and JAMES H. SULLIVAN, both ofMexico, in the county of Oswego, in the State of New York, have inventednew and useful Improvements in Vehicle-Axles, of which the following,taken in connection with the accompanying drawings, is a full, clear,and exact description.

This invention consists in novel means for securing on an axle thewheel-retaining hub, which is adjustable to compensate for wear andabrasions on the ends of the hub-box and on the hearings in contacttherewith, and effectually prevent rattling of said parts without dangerof unduly binding the same.

The invention is fully illustrated in the annexed drawings, whereinFigure I is alongitudinal section of the end portion of an axle providedwith our improvement. Fig. II is an inner end view of thewheel-retaining hub. Fig. 111 is an outer end view of theisame. Fig. IVis a longitudinal section of the outer end of the axle-spindle, showingour invention as it appears in a plane at right angles to that in whichFig. I is taken; and Figs. V and VI are detached end and side views,respectively, of the jam-nut and set-screwfconnected therewith.

Similar letters of reference indicate corre-' sponding parts.

S represents the spindle of a metallic axle formed with the collar a atthe inner end of the spindle, and screw-threaded at the outer end of thespindle.

B denotes the metallic box, with which the bore of the wheel-hub isusually lined, said box being formed with a shoulder, 12, by which itabuts indirectly against the collar a, a packing-ring, s, of leather orother suitable material being interposed between said parts. The innerend of the box is in the form of a sleeve-extension, c, which laps ontoand our braces the collar a, as shown in Fig. 1 of the drawings.

0 represents the wheel-retaining nut, consisting of a female threadedscrew-cap, which screws onto the outer end of the spindle S, and isprovided with the usual circumferential guard-flange, Z. The inner oropen end of the aforesaid screw-cap O is formed with an annular flange,r, which pro ects toward the box B, and is of a diameter to allow it topass over prevented from turning in the cap, and is guided rectilineallytoward the end of the spindle by lugs e e on the nut projecting intolongitudinal grooves d d in the inner side of the screw-cap. The jam-nutis provided with a screw-threaded eye, in which works thescrew-threaded3jshankl of a"'set-screw, f, inserted through the outerend of the screw-cap G, as shown in Figs. I and IV of the drawings. Theeye in the screw-cap, through which the set-screw passes, is smooth, andby the head of the screw bearing against the outer face of the cap 0 anda collar, 12, attached to the screw at the inside of the cap, the saidset-screw is prevented from moving longitudinally. A pin, m, inserted inthe side of the screw-cap, and projecting into the groove 01 of saidcap, limits the movement of the jam-nut, so as to prevent itsdisengagement from the end of the set-screw and its dropping out of thescrewcap when removed from the spindle.

The box B is adjusted on the spindle by tightening the screw-cap C, soas to bring the ends of the box to proper bearings against thepacking-rings s s, which latter retain the lubricant, and serve toprevent rattling and undue friction. The extension 0 over the collar aserves to hold the packing-ring s in place and to exclude dust. Thescrew-cap O is retained in its aforesaid adjusted position by turningthe set-screw f so as to press the jamnnt n against the end of thespindle.

The flange 1 holds the packing-rings s in place and allows the end ofthe spindle to pass inside of the said flange as the packing-ringsbecome worn, and the screw-cap is set in to compensate for the wear.

We are aware that prior to our invention wheel-retaining screw caps ortaps have been formed with a single screw-threaded eye extendingcompletely through the said caps, and

of uniform diameter throughout the length thereof, one end of which eyescrewed into the end'of the spindle of the axle, and a setscrew orso-called temper-screw was inserted in the outer end of said eye to abutagainst the end of the spindle; but such-acoustruction and combinationof parts requires the set-screw to be as large as the screwthreaded endof the spindle, and the large hole through the cap weakens the same;furthermore, such set-screws are more liable to work out of the cap andbecome lost,- all of which defects are obviated by our improvements.

What we claim as new, and desire to secure by Letters Patent. is'* g 1.In combination with the spindle and its wheel-retaining screw-cap, aj'am nu't guided rectilineally in said cap, and a set-screw in" 20serted through the end of the" cap, and restrained from longitudinalmovement, and having its screw-threaded end working in the jam-nut,substantially as set forth and shown.

I 2. In combination with the spindle S and box B the screw-cap 6,provided internally with longitudinal grooves d d, the jam-nut n, seatedloosely in the screw-cap and provided with lugs e e, entering theaforesaid grooves, and the set-screw f, inserted through the outer endof the screw-cap and provided with a head and a collar, respectively, atthe outside and inside of said cap, and engaging a screwthreaded eye inthe jam-nut, substantially as describedand shown.

In testimony whereof we have hereunto signed our names and affixed ourseals, in the presence of two attesting witnesses, at Syracuse, in thecounty of Onondaga, in the State of New York, this 7th day of October,1884.
